cors

cors demo

Here we demonstrate an implementation of cross-origin resource sharing.

In order to fully demonstrate this feature, we must show three things:

1. A server that provides SSE EventSource information http://localhost:8081/
2. A client with a white-listed origin that can reach that information http://localhost:8080/listener.html
3. A client with a non-white-listed origin that cannot reach that information http://localhost:8082/listener.html

To demonstrate this, begin three running instances of this application on ports 8080, 8081, and 8082 (using lein run 808X). Visit the listener.html addresses above. Open your javascript console and click the link on the page to start the event listener for each page.

Thanks

This samples uses the EventSource polyfill from Yaffle/EventSource.

Configuration

To configure logging see config/logback.xml. By default, the app logs to stdout and logs/. To learn more about configuring Logback, read its documentation.
